Abstract
The global coronavirus disease 2019 (COVID-19) pandemic has a detrimental impact on public health. COVID-19 usually manifests as pneumonia, which can progress into acute respiratory distress syndrome (ARDS) related to uncontrolled TH17 immune reaction. Currently, there is no effective therapeutic agent to manage COVID-19 with complications. The currently available anti-viral drug remdesivir has an effectiveness of 30% in SARS-CoV-2-induced severe complications. Thus, there is a need to identify effective agents to treat COVID-19 and the associated acute lung injury and other complications. The host immunological pathway against this virus typically involves the THαβ immune response. THαβ immunity is triggered by type 1 interferon and interleukin-27 (IL-27), and the main effector cells of the THαβ immune response are IL10-CD4 T cells, CD8 T cells, NK cells, and IgG1-producing B cells. In particular, IL-10 exerts a potent immunomodulatory or anti-inflammatory effect and is an anti-fibrotic agent for pulmonary fibrosis. Concurrently, IL-10 can ameliorate acute lung injury or ARDS, especially those caused by viruses. Owing to its anti-viral activity and anti-pro-inflammatory effects, in this review, IL-10 is suggested as a possible treatment agent for COVID-19.

Abstract
The effects of four cosmetic surfactants on interleukin (IL)-1α and IL-8 release from human keratinocytes were studied to investigate the feasibility of using these effects for the prediction of the irritation potential of chemicals. After exposure of cells to surfactants, the amounts of IL-1α and IL-8 released into culture medium were measured by ELISA. Cytotoxicity was evaluated by using the neutral red uptake (NRU) cytotoxicity assay. Cytokine release was increased 7–15 times by sodium lauryl sulphate (SLS), laurtrimonium chloride, cocamidopropyl betaine (CPB) and Oleth-5 at cytotoxic concentrations. IL-8 release was increased 3–4 times by SLS, CPB and Oleth-5 at subcytotoxic concentrations. After exposure to SLS, IL-1α was released within 1 hour, suggesting that IL-1α release is associated with membrane damage, whereas IL-8 release continued for 24 hours, suggesting that IL-8 was produced within the cells. Cytotoxicity tests and IL-8 release assays were also performed on seven other surfactants. The results show that moderate irritants CPB and PEG-4 dioleate, which have weak cytotoxic effects, significantly increased IL-8 release from human keratinocytes. It is suggested that measurement of IL-8 release is useful for predicting the irritation potential of chemicals which cannot be detected by using the NRU cytotoxicity assay.

Abstract
LECT2 is a chemotactic protein to neutrophils. A recombinant six-histidine-tagged human LECT2, (His)(6)-LECT2, was expressed in E. coli using a pET21a(+) vector. The (His)(6)-LECT2 was purified from the soluble fraction in E. coli as a single band in sodium dodesyl sulfate/polyacrylamide gel electrophoresis using three steps of column chromatography with Ni(2+)-charged nitrilo-triacetic acid (Ni-NTA) agarose, DEAE-Sepharose, and CM-Sepharose. The purified (His)(6)-LECT2 was yielded with 96 µg from the soluble fraction of 1,500 ml culture of E. coli. The circular dichroism spectrum of (His)(6)-LECT2 showed the folded structure, which is rich in β-sheet structure and rare in α-helix.

Abstract
The ornithine-containing lipid (OL) and the serineglycine-containing lipid (SGL) of Flavobacterium activated and modulated the functions of human polymorphonuclear leukocytes (PMNs). The OL and the SGL strongly activated fMet-Leu-Phe- and interleukin-8-induced chemotaxis of PMNs at the concentration of 0.1 microg ml(-1), and a synthetic OL also activated the function of PMNs. Further, the OL strongly activated O(2)(-) production from PMNs. Although the OL and the SGL slightly modulated myeloperoxidase release from PMNs, inhibition effects of their component fatty acid analogues were observed. O(2)(-) production-inducing activity is a common biological activity between the OL and bacterial lipopolysaccharides, but OL and SGL, unlike lipopolysaccharide, are potent activators of PMN chemotaxis.

Abstract
We previously reported the purification and amino acid sequence of a novel neutrophil chemotactic protein termed LECT2 (leukocyte cell-derived chemotaxin 2). In this paper we report molecular cloning of human and bovine LECT2 cDNAs based on the amino acid sequence of the purified protein. The deduced amino acid sequence of human LECT2 (hLECT2) shows an 86% identity to bovine LECT2 (bLECT2). The deduced primary structures of LECT2 were highly homologous to the repeated units of Mim-1 protein (myb induced myeloid protein-1). The mim-1 gene is one of the known myb target genes and is specifically expressed in normal and transformed immature granulocytes in the chicken. Northern blot analysis of normal human tissues demonstrated that the hLECT2 gene is specifically expressed in the adult and fetal livers. In addition, several human hepatoma cell lines also expressed LECT2 mRNA, suggesting that hepatic cells in the liver produce LECT2 protein.

Abstract
A recombinant human neutrophil chemotactic protein LECT2 (rhLECT2) was purified as a 16-kDa protein from the culture fluids of stable transfectants derived from CHO cells (clone C1D8-1) and L929 cells (clone L2E4-1). The N-terminal amino acid sequence of the protein secreted by both clones were homologous to the previously described bovine LECT2. We produced polyclonal and monoclonal antibodies against rhLECT2 and investigated secretion of LECT2 protein in six human hepatoma cell lines, which express LECT2 mRNA, and in hepatocytes of normal human livers by a sandwich enzyme-linked immunosorbent assay and by immunostaining using the antibodies, respectively. We revealed that five of six hepatoma cell lines secreted LECT2 into culture fluids at concentrations of 30-135 ng/mg. We also demonstrated that the cytoplasm of human hepatocytes was diffusely stained, although periportal hepatocytes tended to be weakly and granularly stained by immunostaining. These results indicated that the novel protein was expressed in hepatocytes and suggested an important role of LECT2 in the cells in addition to the activation of neutrophils.

Abstract
We purified a neutrophil chemotactic factor from a culture fluid of the PHA-activated human T-cell leukemia SKW-3 cells. The factor showed a 16-kDa basic protein by Tricin-SDS-polyacrylamide gel electorophoresis and analysis of amino acid composition. The primary amino acid sequence revealed that the chemotactic factor was significantly different from other known chemotactic factors, indicating a novel protein designated LECT2. The sequence revealed homology with the myb-induced myeloid protein-1 (Mim-1), which is expressed from gene in immature and normal granulocytes of chicken. Its biological function had not yet been identified. LECT2 and Mim-1 may be involved in the regulation of neutrophil functions in an as yet unidentified way.

Abstract
Molecular cloning of canine interleukin-8 (IL-8) was performed to establish a basis for its investigation in the canine immune system. From a cDNA pool constructed from LPS-stimulated popliteal lymph node cells, canine IL-8 cDNA covering the whole coding region was amplified by polymerase chain reaction. The nucleotide sequence of a canine IL-8 clone, designated pcIL-8#38, was highly similar to those of human, rabbit and porcine IL-8, and comprised 353 bp with an open reading frame that encoded 101 amino acids. Analysis of the deduced amino acid sequence of insert DNA in pcIL-8#38 showed 76.5, 80.2, and 87.0% similarities with human, rabbit and porcine IL-8 proteins, respectively. Insert DNA of pcIL-8#38 was transferred to a mammalian expression vector, pcDL-SR alpha 296, and transfected into Cos7 cells. The supernatant of the transfectant had neutrophil chemotactic activity when it was examined by the neutrophil migration assay, suggesting that our cloned cDNA was biologically active. The cloned canine IL-8 cDNA will be useful for canine inflammatory disease and comparative immunology research.

Abstract
AIMS To investigate the expression of interleukin-8 (IL-8) in Helicobacter pylori infected normal and neoplastic gastroduodenal mucosa, and in established gastric cancer cell lines. METHODS Immunofluorescence techniques were used to localise IL-8 in cryosections of gastric (n = 25) and duodenal (n = 17) endoscopic biopsy specimens an in resected gastric tumour tissue samples from 16 patients. Two gastric cancer cell lines (Kato 3 and MKN 45) were examined for IL-8 protein expression by immunofluorescence and for the presence of IL-8 mRNA by reverse transcription followed by the polymerase chain reaction (RT-PCR). RESULTS IL-8 was localised to the epithelium in histologically normal gastric mucosa, with particularly strong expression in the surface cells. IL-8 expression was also a feature of surface epithelium in the duodenal bulb, but was much reduced in the second part of the duodenum. In chronic H pylori-associated gastritis gastritis gastric epithelial IL-8 expression was increased and expression of IL-8 within the lamina propria was evident. By contrast, large areas of IL-8 negative epithelium were observed in the body mucosa of a subject with Ménétrier's disease. In gastric carcinoma the tumour cells were positive for IL-8. IL-8 was also detected by immunofluorescence in unstimulated Kato 3 and MKN 45 cells, and constitutive IL-8 gene expression in these cell lines was confirmed by detection of IL-8 mRNA by RT-PCR. CONCLUSIONS Immunoreactive IL-8, a potent neutrophil chemotactic and activating factor, is present in the epithelium of both normal and inflamed gastric mucosa with increased expression in the latter. There is site dependent variation in epithelial IL-8 expression within the gastroduodenal mucosa. The expression of the pro-inflammatory cytokine IL-8 in gastric carcinoma cells may influence peritumoural cellular infiltrates.

Abstract
We cloned a 2.3-kb sequence homologous to the gene (hIL8) encoding human interleukin-8 (hIL-8) from the canine genome. The sequence may encode an 11.3-kDa protein consisting of 101 amino acids, sharing 75, 80 or 85% identity with the human, rabbit or porcine IL-8 proteins, respectively. Southern and Northern blot analyses indicated that the cloned sequence appeared to exist as a single copy in the canine genome, and that its expression was inducible with lipopolysaccharide in canine mononuclear cells, respectively. Thus, it seems very likely that the cloned gene is a canine homologue of hIL8.

Abstract
We looked for chemotaxin/interleukin 8 (CT/IL-8) activity in the culture fluids of 97 human leukemia cell lines and found it in two of the T cell lines, six of the myeloid cell lines, and one of the normal B-cell lines. It was particularly strong in the culture fluids of two cell lines. These cell lines secreted a chemotactic protein into the culture fluids under certain conditions of stimulation with phorbol-12-myristate 13-acetate (PMA), lipopolysaccharide, or hemagglutinin-P. A myeloid leukemia cell line, ML-1, secreted an inducible chemotaxin when stimulated with PMA (1 ng/ml) for 24 h. We purified the chemotaxin from ML-1 cell culture fluid using an improved procedure: concentration with DEAE-Sepharose CL-6B and CM-Sepharose CL-6B, CM-Sepharose column chromatography, and reverse-phase 5TMS-300 column on HPLC with the retention time coinciding with that of LUCT/IL-8 [Suzuki et al., 1989, J. Exp. Med. 169, 1895]. The yield was 200 micrograms protein from 6 liters of the culture fluid. The N terminus of CT/IL-8 was AVLPR-SAKELRXQXIKTYSK- - -, the same as that of LUCT/IL-8, which is constitutively secreted from lung giant cell carcinoma LU65C cells. The optimal concentration in the chemotactic activity of CT/IL-8, equivalent to that of bacterial chemotactic peptide fMet-Leu-Phe (10 nM), was found to be 5 nM. The results show that this chemotaxin is identical to LUCT/IL-8.

Abstract
The production of interleukin 8 (IL-8), a neutrophil chemotactic factor, and its amino acid sequence were examined in glioblastoma cell lines in vitro. Neutrophil chemotactic activity was demonstrated in 9 conditioned media of 15 human glioblastoma cell lines. Tumor necrosis factor (TNF)-alpha stimulated secretion of the activity in 7 lines and induced secretion in 4 other lines. ELISA quantification disclosed that the conditioned media contained interleukin 8 (IL-8) in an amount equivalent to the chemotactic activity. The IL-8 secretion increased with the stimulation by TNF-alpha. Northern blot analysis and the RT-PCR method confirmed expression of mRNA in the glioblastoma cells and its augmentation by TNF-alpha and/or IL-beta. Reversed-phase HPLC following ion-exchange chromatography revealed that the chemotactic activity was a single peptide, which was determined to be IL-8 by the retention time and ELISA. Furthermore, amino acid analysis disclosed that a major part of the glioblastoma-cell derived IL-8 peptide was 77 amino acid IL-8 (IL-8(77); with the N-terminal sequence AVLPRSAKELRCQCI-).

Abstract
Responses and susceptibility of 14 human glioblastoma cell lines to human natural tumor necrosis factor-alpha (TNF) were studied in vitro. Susceptibility of glioblastoma cells to TNF varied in experimental conditions applied. Most of glioblastoma cell lines were resistant to cytotoxic activity of TNF in a MTT assay at concentrations below 16 U/ml for 72 h exposure. However, TNF at higher dose, in prolonged exposure and against low density of target cells was antiproliferative for certain glioblastoma cultures. TNF exposure at 10 U/ml for 48 h suppressed DNA synthesis in 9 of 14 glioblastoma cultures, but increased in 3 cultures. In addition, colony forming assay showed anti-clonogenic activity of TNF in 5 of 6 glioblastoma cell lines tested. In spite of their low susceptibility to TNF, glioblastoma cells well responded to TNF stimulation at low dose (10 U/ml) for a short period in the absence of cell damage. Productions of Interleukin-6 (IL-6), IL-8-like activity, granulocyte-macrophage colony stimulating factor (GM-CSF), prostaglandin E2 (PGE2) and manganous superoxide dismutase (Mn-SOD) were enhanced or induced by the low-dose TNF stimulation. Mn-SOD, a protein protective against oxidative cell damage, was well induced in time- and dose-dependent manner, however did not correlate with TNF resistance. Whereas the levels of PGE2 in TNF-susceptible cell lines, H-4 and SF-188, were higher than those of other lines. In conclusion, most of glioblastoma cells are resistant to TNF cytotoxic effects, but highly responsive to TNF stimulation. Its effect on glioblastoma cells appears to modulate cell differentiation rather than to kill the cells.

Abstract
To elucidate the role of tumor necrosis factor alpha (TNF alpha) as a biological response modifier, we studied cellular and cytokine responses of the central nervous system to TNF alpha administered intracranially in a phase I clinical trial for patients with malignant gliomas. Six patients received injections of TNF alpha (1.25 x 10(3)-10 x 10(3) U/injection) into the tumor cavities, and regional fluids (RF) and lumbar cerebrospinal fluids (CF) were serially sampled before and after the injections. Recruitment of neutrophils occurred, mostly peaking 8 h after TNF alpha injection, and fewer numbers of CD4+ T cells and monocytes/macrophages migrated, subsequently peaking at 24 h. The CF leukocytosis persisted for 48 h and was associated with an increased level of neutrophil chemotactic activity in the CF. This neutrophil chemotactic activity was attributed to interleukin-8 (IL-8) by HPLC. The level of IL-6 activity in the CF and RF consistently increased; beginning 2 h after TNF alpha injection and reaching the maximum between 8 h and 12 h. It returned to the basal level within 48 h. IL-1 beta was detected in the CF of three patients, its level peaking at 8 h. Prostaglandin E2 also increased after injection of TNF alpha, peaking between 4 h and 12 h and then gradually decreasing. Transforming growth factor beta was found in all cases tested and one patient showed a significant change after TNF alpha injection. IL-2 activity, interferon alpha (INF alpha) activity, IFN beta, and granulocyte/macrophage-colony-stimulating factor were not detected in the CF or RF. In conclusion, TNF alpha is biologically effective in inducing migration of immune cells and generating multiple cytokine responses in the human central nervous system.

Abstract
We previously reported that a 64-kDa protein (p64) in human polymorphonuclear leukocytes (PMN) was phosphorylated with [gamma-32P]ATP under a micromolar concentration of glucose in a cell-free system. The present paper presents the results of analysis of phosphorylation reaction and the identification of phosphoprotein. The findings that p64 was also phosphorylated with glucose-6-[32P]phosphate and that phosphorylation was inhibited with mannoheptulose suggested that the reaction was mediated by hexokinase. In fact, it was found that [32P]phosphate in glucose-6-[32P]phosphate was incorporated into either p64 or rabbit muscle phosphoglucomutase and that glucose-6-phosphate formation from glucose and ATP was detected in over 100-kDa fraction of PMN cytosol. These results showed that p64 was phosphoglucomutase in PMN and that phosphate incorporation into p64 was a conversion of a phosphate group in glucose-6-phosphate produced by hexokinase. It was further demonstrated by analysis of two-dimensional electrophoresis that p64 phosphorylated with glucose induction was different from another 64-kDa protein phosphorylated by stimulation with formyl-methionyl-leucyl-phenylalanine in vivo.

Abstract
We examined the production of interleukin-8 and interleukin-6 by 30 human carcinoma cell lines. Serum levels of interleukin-8 were measured in 14 patients with hepatocellular carcinoma by enzyme-linked immunosorbent assay and Northern blotting. Furthermore, serum interleukin-8 was also investigated in a nude mouse bearing a tumor of the HuH7 hepatoma cell line producing interleukin-8. Of the 30 cell lines, 29 (96.7%) constitutively produced interleukin-8, and 19 of the 29 (65.5%) were high producers (> 1 ng/ml culture supernatant). Among the high producers, 4 cell lines released both interleukin-8 and interleukin-6. Interleukin-6 was constitutively produced by 17 of the 30 (56.7%) cell lines, 4 of which (23.5%) were high producers (> 1 ng/ml). By Northern blot analysis, mRNAs of interleukin-8 and interleukin-6 were detected in producing cell lines. Of 14 patients with hepatocellular carcinoma 4 (28.5%) showed increased levels of serum interleukin-8. Furthermore, inoculation of the HuH7 hepatoma cell line which produced the highest amount of interleukin-8 into a nude mouse resulted in tumor production accompanied by an elevated level of human interleukin-8 (646 pg/ml) in the peripheral blood. Thus, interleukin-8 is constitutively and commonly produced by various carcinoma cell lines. The production of interleukin-8 by carcinoma cells may be related to the elevation of serum interleukin-8 in patients with hepatocellular carcinoma. Finally, these cell lines may be valuable for studying the relationship between interleukin-8 and cancer.

Abstract
Cellular constituents of the alveolar-capillary wall may be key participants in the recruitment of polymorphonuclear leukocytes to the lung through the generation of the novel neutrophil chemotactic peptide interleukin-8 (IL-8). This interaction appears to occur via the ability of human alveolar macrophage (AM)-derived monokines, tumor necrosis factor (TNF), and interleukin-1 (IL-1) to induce gene expression of IL-8 from pulmonary type II-like epithelial cells (A549). Northern blot analysis demonstrated that steady-state IL-8 mRNA expression, by either TNF- or IL-1 beta-treated A549 cells, occurred in both a dose- and time-dependent fashion. Similarly, extracellular antigenic IL-8, as assessed by specific ELISA, was expressed from TNF- or IL-1 beta-stimulated epithelial cells in a time-dependent fashion with maximal IL-8 antigen detected at 24 h poststimulation. Immunohistochemical staining utilizing rabbit anti-human IL-8 antibody identified immunoreactive, cell-associated IL-8 antigen as early as 8 h post-TNF or IL-1 beta stimulation. A549-generated neutrophil chemotactic bioactivity paralleled IL-8 steady-state mRNA levels. Signal specificity was demonstrated in this system as IL-8 mRNA or protein expression by lipopolysaccharide (LPS)-treated A549 cells was not different from unstimulated cells. Although LPS did not serve as a direct stimulus for the production of IL-8 by type II-like epithelial cells, the condition media from LPS-challenged AM induced a significant expression of IL-8 mRNA by the A549 cells. 24-h conditioned media from LPS-treated cells was as potent as either IL-1 beta or TNF in generating steady-state IL-8 mRNA by A549 cells. Preincubation of LPS-treated AM-conditioned media with anti-human TNF or IL-1 beta neutralizing antibodies resulted in significant abrogation of IL-8 gene expression by A549 pulmonary epithelial cells. These findings demonstrate potential cell-to-cell communication circuits that may be important between AMs and pulmonary epithelial cells during the recruitment phase of acute lung inflammation.

Abstract
An inflammatory reaction was induced in vivo by injection of zymosan into the peritoneal cavity of the rabbit. The inflammatory exudate was found to contain oedema-inducing and neutrophil chemoattractant activity when assayed in rabbit skin in vivo, using 125I-albumin and 111In-neutrophils. This activity was additional to that of complement fragment C5a, which was removed by an affinity gel. Two chemoattractants were isolated by cation-exchange, gel-filtration and reversed-phase h.p.l.c. One of these, which ran as a single band of 6-8 kDa on SDS/PAGE, was subjected to N-terminal sequence analysis without reduction and alkylation of cysteine residues. Positive identification of 28 of the first 31 amino acids revealed a rabbit homologue of interleukin-8 (75% sequence identity with human interleukin-8). The demonstration of interleukin-8 as a major neutrophil chemoattractant in an inflammatory reaction in vivo provides the basis for further investigations into the role of this cytokine in the inflammatory process.

Abstract
Glucose-stimulated phosphorylation of 64-kDa protein using a greater than 30 kDa fraction of human polymorphonuclear leukocytes in a dose-dependent fashion with 33 microM for maximum stimulation and 1.4 microM for ED50. None of the glucose derivatives and metabolites of glycolysis stimulated phosphorylation, but glucose-1-phosphate, glucose-6-phosphate, fructose-6-phosphate and fructose-1,6-diphosphate inhibited the glucose-stimulated phosphorylation, strongly suggesting phosphorylation by glucose-regulated protein kinase. Cyclic nucleotides and the protein kinase inhibitors H-7, H-8, W-7 and staurosporine did not affect phosphorylation.

Abstract
A 1.9-kb fragment containing an interleukin-8 (IL-8) coding region was amplified by the polymerase chain reaction (PCR) from the genomic DNA of human lung giant cell carcinoma LU65C cells that produce LUCT/IL-8 with N-terminal sequence of AVLPR. The coding region was found to consist of 4 exons and 3 introns as identical as that of the gene of MDNCF/IL-8 lacking N-terminal AVLPR. PCR using genomic DNAs from human polymorphonuclear leukocytes and mononuclear cells also provided the same 1.9-kb fragment as that from LU65C genomic DNA. Thus, it seems likely that human cells possess IL-8 genes with the homogeneous coding region so that they may first produce the same mature protein with N-terminal AVLPR (= LUCT) which was then truncated.

Abstract
A synthetic peptide, AVLPRSAKEL (LU10), the N-terminal amino acid sequence of chemotactic protein (LUCT/IL-8), showed chemotactic activity to polymorphonuclear leukocytes (PMN) with an ED50 of 5 nM for comparable to that of LUCT. Native LUCT and LU10 specifically induced the phosphorylation of 64 kD protein of PMN, and serine residue in the 64 kD protein was major phosphorylated amino acid. Furthermore, native LUCT enhanced the release of myeloperoxidase and beta-glucuronidase from PMN in the presence of cytochalasin B and FMLP, but LU10 did not. These results strongly suggest that the active site for both chemotactic stimulation and 64 kD protein phosphorylation is localized on the sequence of N-terminal 10 amino acids of LUCT.
